In triangle PQR, PR = 23mm, QR = 39mm, and m<R = 163 degrees. Find the area of the triangle to the nearest tenth.
Schach [20]

Answer: 131.1287 square mm (approx)

Step-by-step explanation:

The area of a triangle,

A=\frac{1}{2} \times s_1\times s_2\times sin \theta

Where s_1 and s_2 are adjacent sides and \theta is the include angle of these sides,

Here PR and QR are adjacent sides and ∠R is the included angle of these sides,

Thus, we can write,

s_1 = PR= 23\text{ mm}, s_2=QR=39\text{ mm} and \theta = 163^{\circ},

Thus, the area of the triangle PQR,

A=\frac{1}{2} \times 23\times 39\times sin163^{\circ}

A=\frac{262.257419136}{2} = 131.128709568\approx 131.1287\text{ square mm}

Nick is training for a biathlon he will swim every 6 days and bicycles every eight days on what days will he both swim and bicyc
Bumek [7]
On every 24th day because 6 and 8 are both multiples of every 24th number like 24.
6×4=24 8×3=24
6×8=48 8×6=48
48/2=24
6×12=72 8×9=72
72/3=24 ...... and it keeps going

So the answer is every 24th day Nick will both swim and bike.

which statement best explains why the sum of the areas of the two white squares in figure 2 is the same as the area of why squar
Stella [2.4K]

Answer:

"In each figure the total area is equal and the area of the 4 triangles is equal, so the remaining white area in each figure must also be equal."

Step-by-step explanation:

Both figures make up congruent squares, and they are made up of 4 congruent triangles, so the white area in between must be equal between the two figures

Anyone know how to solve this is for calculus?
ASHA 777 [7]
So thing of that weird little circle as “of”

Thus: “g of h of x” or g(h(x)). First find h(x) by plugging x in for h and then plug whatever h(x) is in to g.

Ex. If h(x)= 4x + 2 And g(x)= 2x + 5,

g(h(x))= 2(4x + 2) + 5 = 8x + 4 + 5 = 8x + 9
